IMPROVEMENT IN WOODEN PISTON-RODS FOR DEEP WELLS.

Specilcation forming part of Letters Patent N0. 52,355, dated January 30, n1866.

To all whom t may concern:

' Be it known that I, E. N. ALLEN, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Sucker-Rods for Pumps; and l do hereby declare that the following is a full and complete description of the same, reference being had to the accompanying drawings, makinga part of this specilication, in Which Figure l is a perspective view of a portion ofthe rod, showing the manner of connecting the coul'iling-plates to the sections of the rod. Fig. 2 is a perspective view of a part ot' one of the coupling-plates detached from the rod. Fig. 3 is a vertical section through a portion of the rod.

Lilie letters of reference refer to like parts in the several views.

My improvement relates to the manner of connecting the coupling to the sucker rods, as hereinafter described.

s ln Fig. l, A and B represent sections ot' a sucker-rod in which the coupling-plates are secured, that are united or coupled together bythe screw D, as indicated by the dotted lilies. The coupling-plates F, inserted and secured in the ends of the sections ofthe rod, are equal in width one way to the rod, and across the other they taper toward the ends, as shown in Fig. l. The plates are secured in the sections or wooden part H of the rod by means of bosses a formed on and projecting from the sides of the plates, as represented in Fig. 2, that extend into the wood, and the edges of the plates are shouldered out as at c, on which wire It is wrapped that passes around depressions b cut or shouldered out on the rod.

The solid Wooden rod, in order to lit on the plate and be connected to it, is bored out so as to receive the bosses c of the couplingplate, and from one bored opening to the other the rod is slotted or scarfed out, according to the width ot' the plate,'when the plate can be putin the rod from one side, the bosses litting into the bored openings, and the places shouldered out atc on the'edges of the plate correspond or lit into place with the depressions b shouldered or turned out on the rod, round which the copper wireh is Wrapped, whereby the wooden part H of the rod is securely fastened to the plate, which connection is rendered very lirm and strong', not only by the wire wound around the plate and rod, but also by means of the bossed projections a extending into the wood from the plate.

In the ordinary mode ot' attaching the coupling-plates to the rod, when the Wood becomes soft by the water the fastenings are loosened, causing the pump to stop, and to re. pair it is accompanied with much difficultyv and expense, which are obviated by having a rod constructed as herein described.

In the ordinary pump-rod, the wood being softened by the oil and water, the rivets be come loose,work out, and drop down into the barrel or valves of the pump, producing a leakage of the rod or valves, either breaking the rod or injuring the valves so as to stop the working of the pump.

One or more bosses may be used, and th ey can be of an angular form; but I prefer them as herein described, being more easily and conveniently litted to the rod.

NVhat I claim as my improvement, and desire to secure by Letters Patent, is-

The platesy F, provided with one or more bosses, a, in combination with the section A or B of the rod, arranged and secured together substantially as and for the purpose set forth.

E. N. ALLEN.
